Powers/Hazard: Faerzress

Powers/Hazards: Faerzress

Faerzress is a type of magical radiation that suffuses many parts of the Underdark in the Forgotten Realms setting. It serves both as a source of mutations and as an environmental effect that interferes with teleportation and divination. Cool! Let's convert it to GURPS.

First, Information spells and similar magical abilities that are cast within a faerzress-infused area or that target a subject in such an area take a -5 penalty on their casting/usage rolls. Teleportation spells and abilities with their origin or destination points within a faerzress-infused area take a -5 penalty on their casting/usage rolls. Abilities that do not require rolls work with a halved efficiency.

Faerzress works similar to Weird Radiation (GURPS Powers: The Weird, p. 37). Faerzress-infused zones vary in intensity from 1 rad per week to 5 rads per hour. Regardless of the intensity, the magic interference effect stays the same. Thus, creatures that want to benefit from the faerzress' protection from divination prefer very low intensity zones. If you want to determine the zone's intensity randomly, use the following table:

1d	Intensity
1-2	Low (1d rads per week)
3-4	Medium (1d rads per day)
5-6	High (1d rads per hour)

On exposure to faerzress (but no more than once per day, for continued exposure to a given source), roll vs. HT at the penalty for rads given by the Radiation Effects Table (p. B436) and substitute the following effects:

    A: You gain a random temporary mutation.

    B: You gain a random lasting mutation.

    C: You gain a random permanent mutation.

    D: You gain 2 random permanent mutations.

    E: You gain 1d random permanent mutations.

Use Duration of Crippling Injuries (pp. B422-423) to determine how long these last. Faerzress dosage accumulates, and partially diminishes over time, in the same way as realistic radiation.

When a creature accumulates HT/3 (rounded down) permanent mutations, it must make a daily HT roll. A failure means an instant death.

Determine the mutations using the following table.
